Applying a curve modifier to an extruded plane causes plane to become a line
There was a scaling problem (even though I applied scaling &amp; rotation) but I couldn't find the Transform > Radius that Ramos described. I found that if I zoomed in far enough, what I thought was a line was the horribly deformed extruded plane. I tried numerous re-scaling of both the plane &amp; the curve, and with the hint that Mr Zak supplied, went to the Bezier curve's shape properties, and unchecked 'radius' (path/curve deform) and set Minimum's Smooth (Twisting) value from 0 to 6.00. Mostly by luck(?) I got the desired results. Mission accomplished! Thanks all.
